This signaling technique lowers the output voltage levels of 5-V differential standard levels (such as EIA/TIA-422B) to reduce the power, increase the switching speeds, and allow operation with a 3.3-V supply rail. Any of the quad differential receivers will provide a valid logical output state with a ±100-mV differential input voltage within the input common-mode voltage range. The input common-mode voltage range allows 1 V of ground potential difference between two LVDS nodes. The intended application of this device and signaling technique is for point-to-point baseband data transmission over controlled impedance media of approximately 100 Ω. The transmission media may be printed-circuit board traces, backplanes, or cables. The ultimate rate and distance of data transfer is dependent upon the attenuation characteristics of the media, the noise coupling to the environment, and other system characteristics. The SN65LVDS048A is characterized for operation from –40°C to 85°C.

VCC is always higher than RIN+ and RIN– voltage, RIN– and RIN+ have a voltage range of –0.2 V to VCC–VID/2. To be compliant with ac specifications the common voltage range is 0.1 V to 2.3 V. 5. The VCMR range is reduced for larger VID, Example: If VID = 400 mV, the VCMR is 0.2 V to 2.2 V. The fail-safe condition with inputs shorted is not supported over the common-mode range of 0 V to 2.4 V, but is supported only with inputs shorted and no external common-mode voltage applied. A VID up to VCC–0 V may be applied to the RIN+ and RIN– inputs with the common-mode voltage set to VCC/2. Propagation delay and differential pulse skew decrease when VID is increased from 200 mV to 400 mV. Skew specifications apply for 200 mV < VID < 800 mV over the common-mode range. 6. Output short circuit current (IOS) is specified as magnitude only, minus sign indicates direction only. Only one output should be shorted at a time.

The LVDS receiver is like most differential line receivers, in that its output logic state can be indeterminate when the differential input voltage is between –100 mV and 100 mV and within its recommended input common-mode voltage range. TI’s LVDS receiver is different in how it handles the open-input circuit situation, however. Open-circuit means that there is little or no input current to the receiver from the data line itself. This could be when the driver is in a high-impedance state or the cable is disconnected. When this occurs, the LVDS receiver will pull each line of the signal pair to near VCC through 300-kΩ resistors as shown in Figure 10. The fail-safe feature uses an AND gate with input voltage thresholds at about 2.3 V to detect this condition and force the output to a high-level regardless of the differential input voltage. VCC 300 kΩ 300 kΩ A Rt = 100 Ω (Typ) Y B VIT ≈ 2.3 V Figure 12. Open-Circuit Fail Safe of the LVDS Receiver It is only under these conditions that the output of the receiver will be valid with less than a 100-mV differential input voltage magnitude. The presence of the termination resistor, Rt, does not affect the fail-safe function as long as it is connected as shown in the figure. Other termination circuits may allow a dc current to ground that could defeat the pullup currents from the receiver and the fail-safe feature.
